(Newser) – Workers at Japan's Fukushima Dai-ichi nuclear plant were evacuated again today after smoke rose from one of the damaged reactors, the AP reports. The cause of the smoke was not yet clear. Earlier today, a village about 20 miles from the plant was advised by the Health Ministry its tap water had elevated levels of iodine and should be avoided. Still, the government said the radiation levels were too small to pose an immediate health risk.

Yesterday, a senior US nuclear official said on C-SPAN that though radiation levels at the damaged nuclear plant were still high, "we have some indications that they may be coming down," the Los Angeles Times reports. Even so, he added, "it's difficult to obtain accurate information." Levels at the plant are reportedly in the hundreds of millisieverts per hour; the exposure limit for Japanese workers is 250 millisieverts per year.
